To all whom 'it may concern:

.Be it known thatl, JOHN lll. PAUL, a citizenof the United States, residing at Kitstruction 'thereof as will be hereinafter fully described and pointed out in the claims.

Figure' 1 showsv a section on the line 1-1, 1--1, 1**--1b in Fig.l 2. Fig. 2 a section on the line 2 2 in Fig. 1. Fig. `3, a section on the line 3 3 in Fig. 1. Fig. L1, a side. elevation of a. segmentof the auxiliary frame showing the stops for the basket. Figj, a sectionl through the same mechanism. F ig. G, a side elevation, with parts removed to better show the' construction, of the shift mechanism. l

A marks the main frame of the machine which m'ay beof any desired construction.

The platen B is mounted on this frame and is provided with the ordinary ribbon spools C andtype bar guides D.

The machine shown is-of the front strike type` lint in all respects limited to this type of machine.

-Xiranged Within thenain frame is an auxiliary frame E. The auxiliary frame is Aformed ofsheet .metal The sheet metal sides 6,15 have the rear ends e2 and front ends e3. The sides are provided with the notch-es e* and e? which engage the pins o and a", extendinof inwardly from the main frame. Th notch Ve5 is cut away atie to perlnsertion. of the-'auxiliary frame InaV general way this construction' is shown in a' patent granted 'to me on October v'Zt-li, 1908,;#9-on998. .l 4

The type-basket F hasthe segijnent f arranged 1n a vertical planefinfsuch position relatively to the platen as to form' the printing point.l thereon in front of the platen. The basket Vhas the supporting legs: F to which are pivotally connectedv the 'parallel bars H, H, by,V means of screws 7d h. There are two of these bars H', one above the other, so

at each' side ofthe basket, thns forming two sets of parallel bars. The front ends of these-bars are 'rigidly securedl to the rodsA upper and lower bars respectively at the opposite side of the basket, and vin conse-` quence their paralleling action is rendered more etlicient. These bars guide the ment as it is shifted to a position to producV louer or upper case ii'ul'nfession and main tain the segmentl in substantially the saine plane or at least in planes parallel 'in the ditferent positions. There the basket ik. pivoted on a single pin and shifted, it shifts the angular relation ofthe seginei'itl rela lively to the platen and it is diflicult to maintain the alinemcnt ot' the lifter-cnt typo bars, the change of angle having a flillfercnt effect ou the end type-bars than upon those the desirable feat-ure of a pivotal mounting` is retained.

The type-bars G are mounted on t-l'ie ment F and normally lie toward the front of the machine, and are pivoted on a rod f/ which extends through all. the type bars. They are provided with the type g, each bar having an upper and lower case letter. The rods I are pivotall'y connected ,\vith the heelsl g2 of the type-bars and extend. for` Wardly from ,these through al guide plate li. The rods l are free to more through this guide plate, this plate for-ming a guide for the rods. The perforations through' the' guideplate are arranged in an arc corre.- sponding to the segment. for the typefbars, tf '1e segment being arranged so that the diiferent rods I have', approximately the saine relation -,to the' type bars to which they are attached. Push rods J are arranged beneath the rods I anda proximately parallel to the bars H--H.

hey have the forked ends y' a-11d"`7'l. 'The end j is' pivotaLl-y connected with the bracket 'i' on the rod I and the, forked end j? is pivot-ally'connected to the rock lever K thus formin a link between the -lever K' and rod l. -he rod J' is provided Witli the right andleft screw threads 'js ja which are secured to the ends 7' and P and locked *in 'position by the jam nutj* j By this means the length ofthe rod may be adjusted .so as to give the roper length to each connection. The roer lever K has` the forwardly extending arm 7c. the Whole forming an :ingle lever.4 A' slot lo is arranged inthe arm le. The levers lare. pvot ally mounted on a rod K extending across the auxiliary frame.

The key levers L are rovided with the notches t which engage tie rear plate e* of the auxiliary frame. A; spring, l extends through a yierforation el" 1n rear plate e. It has the downwardly extending portion Z2 and horizontal portion-Z?, The horizontal portion extends through a perforation l* in the key lever. This spring exerts the usual spring tension on the key lever'. The key lever .is provided. with the usual'fin er piece Z5 and the pin Z6 extends from the si eof the key-lever through the slot lc for oonmunieating the movement of the key-lever to the rock-arm 4K. It will readily be seen that upon the depression of the key-lever, the rock-leverK is swung toward the front of the machine and this, acting as a lever of the first order upon the push rod J, aotuates the rod I and consequently the type-bar conneoted with the type-bar ae'tion. The rocklevers K are preferably of different lengths so that the top ends ofthe'levers each pre- Sent about the saine relation tothe rods I. The pins Zs are locatedon the different keylevers in such relation to the levers K as to' givet'o each key-lever the same depression to effect the excursion ofthe type-bar tothe printing point. l

It will be noted that as the basket is shifted for upper or lower ease letters, the rods I aremoved with the basket. The rear ends of the parallel rods H. in'lower case position are slightly below the rods heb so that as the basket is svi-'ung upwardly. vit moves. slightly toward the rear of the machine'. The upper ends of the rods J, it. will be noted, also swing in 'this direotiomtheir inimovementto the type-bar action. To effect' tial position being somewhat nearer the hori-l zontal 'than the. rods The total swing leaves the key-levers in' their normal positionjuftha't is, the front ends of the rods J swin toward the rear of themachine suffi` cient y -tov compensate for the rearward Swingin of the type-basket. or viee versa.

It 1s esirable to get a quick initial returnl this result, I provide'the bar M which is ar ranged in the path; of the. rock levers K.

' The bar M is mounted on the levers M',

these levers being pivoted at m on' the aux' il'iary frame. A sprin m isse'curedto the lever M?. The bar engages v'the rocklevers justprior to' the lend of: their stroke and gives 4tol thema quick, snappy initial returnjmovementf This bar is ickedlup b the rook-levers later than is easible witi the ordinary vspacer bar, and being independ- Vently mounted is free from the frictional disturbances of the universal 'bar'. i 'In Fig.,

2,1 show the usual spacer bar N. A

In order to rovide convenient stops for the shift, I strike out from the sides e-e of the auxiliary frame'the ears ele. p IheV Athe-shift lever 0'.'

screws ei e -are arran ed lin these ears and look nuts e e3 are p aced on the screws.

These screws operate on the in from the basket. l

n a patent issuedto me June 26, 1906, Serial ho. 824,579, lI have shown a reverse shift mechanism. In this application I show an improvement on V the shift 'mechanism shown in my patent. An auxiliary shift lever O is pivotally .mounted on the-screw 0 secured in the side plate e. This'shift lever is provided with the slot o extending each side of the pivotal supporto. A in 02 loperates in this slot. The pin is carrie by a: link o. Thelink o is ivotally connected with he auxiliary shift le-ver pin f extenda pinv fion the basket. .An Aarm @extends 4upwardly from the alixiliary leveeland a spring()H connects the upper' end of this arm with areversingle'ver O2. The reversing le` ver'O2 is p'ivotedv on the screw o and has the Y lshaped end 0 with the arms 01".A An op erating lever G4 'is pivotedato6 on the frame.

This is provided with a slot' 07' which en-V gages a pin o8 on the reversing lever-O2, lVi'th the prts inthe position shown in Fig. 6,-1t will noted that a depression of the shift lever O actin through the link-egon the auxiliary shift ever 0 will depress the' front end of this shift lever and acting 'on' the screw..A O as a fulcrur'n, lift the Atypebasket.'v `When, however, theoperatin'g lever O* is'lifted', the lower end if-the reversing'le vereis moved tow-ardthe right and the arm 01 of the fork engagesthe pin 02 and carries it to the opposite side of a pivot e. At the Sametime it :carriesthe pin '0*3 Awhich is an anchor forthe spring 03 to the opposite sideV of the pivot so'thatit tends to swing the auxiliary lever O'upwardly and the spring s of such strength as-to 'eect this result and therefore normally held thejbasket in the upper position. A depression,=theli of the shift 'lever operatingthrough the link o3A and the'upperend of .the lever O will depress the basket and upon 'the-:release of tthe Y shiftleverthe basket'wifll `be returned toithe upper position `through the iaction .of the spring' O3. I prefer to approximately --bal-' ance' the' weight- -o'fglthe basket; by means'- of the spri 'h2 whieh extends from the plate I to the" ower bars H, On'eof'thes'e springs is arr ngedvat each side-ofthe basket." l
